I've been discovering interesting and insightful videos about the artistic process that previously were unknown to me, and I thought others here might have favorites they could recommend.
These could be a conversation related to a specific production and how it came together or just about theatre and any aspect of the artist process on a more general level.
The one that sent me down the YouTube rabbit hole is this conversation at BAM between Ivo van Hove and Tony Kushner when van Hove's production of Angels was staged at BAM.
